We may be able to explain this.
Let’s start with a slight detour. There is a famous (and cool!) Physics fact about pole vaulters. When a pole vaulter jumps over a bar, his/her center of gravity (CG) need not go as high as the bar which needs to be cleared. In other words, at the top of the jump, the pole vaulter needs to go over the bar and not his/her CG. To achieve this, the pole vaulter arches his/her back forward or backward to be in a situation where Newton’s laws only dictate the trajectories of the CG and not the entire body.
Lynn’s miraculous falling back within the boundary rope is something similar. After the little stumble he has just before he makes his jump, he has his eyes on the ball. Assess the trajectory of the ball, and it looks something like this.
Now Lynn considers jumping straight up to get the ball. Is there a chance he can make it? His jumping ability is limited and there is only a limit to which he can raise his CG. He would not have caught the ball.
However, if he jumped and turned back at the same time, things could look very different even if his jumping ability is considered to be the same.
He does exactly what it takes to take the catch; since his CG is still very much inside the boundary region, he can easily use his body to bring his hands inside the boundary rope eventually using his hands to land safely within the boundary.
So Physics doesn't seem that bad after all! Share this awesome trivia with your friends the next time you get together to watch a cricket match. May the Force (yeah, F=ma) be with you.
